Cons

The Reebok ZigEnergy is a mid-priced men's running shoe. Reebok promotes their Zig line of shoes as their most advanced training shoes to date. The zig-zag sole absorbs the impact of heel strikes and helps to keep propelling you forward, thereby cutting down on the energy your leg muscles have to use by 20%. The forefoot flex grooves, which move with your foot while it steps, also help to make long runs less taxing. The synthetic/mesh upper gives you a comfortable feel that is also durable. The DMX Shear cushionining grooves also help to make the feel of the ZigEnergy comfortable. The Zig shoes all have the same specs, with slightly different exterior designs.
